For reference, the equation for pH is given by: pH=−lg[H +] pH=−lg[H+] pH is given by the negative logarithm of the concentration of hydrogen ions ([H +] [H+]). You can see that pH depends on the …

WebpH is a measure of hydrogen ion concentration, which is measured as a negative logarithm. In other words, acids produce hydrogen ions and alkalis produce hydroxyl ions, so pH is the power of a solution to yield hydrogen ions [H+]. The pH scale ranges from 0 to 14 and indicates how acidic or basic a substance is. A pH of 7 is neutral.

WebpH scale is based on neutral water, where [H +] = [OH –] = 10 -7 For a neutral solution pH = = – log [H +] = – log [10 -7] = +7 pH of strong acid decreases with a limit of 1 and pH of a base increases up to 14 Generally, acids and bases will have a pH between.
